What does the baby name “Kaitlyn” mean?
Kaitlyn is a modern American spelling of the Irish name Caitlin, itself a Gaelic adaptation of Catherine, one of the most enduring and beloved names in the Western tradition, meaning 'pure.'
Origin of the baby name Kaitlyn
Kaitlyn traces its lineage through Caitlin, which is the Irish and Scottish Gaelic form of Katherine. Katherine itself is believed to derive from the ancient Greek name Aikaterine, though its precise etymology is debated: it may connect to Hekate, a Greek goddess, or to the Greek word *katharos* meaning 'pure' or 'clean.' The Irish adaptation Caitlin transformed the classical name through Gaelic phonology into something distinctly Celtic, and Kaitlyn is the most popular phonetic anglicization of that Irish form.
